BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is to sort a variety of products for each product into trucks that are loaded into a sorting station from a manufacturing line and sort them into trucks for each product. As described above, the present invention relates to a trolley sorting device used when sorting trolleys for each product such as loaf of bread, bean jam, croissant, etc. that have flowed from several or more manufacturing lines into predetermined places.

[0002]

2. Description of the Related Art Conventionally, in the case of a bakery factory, various breads such as loaf of bread, bean jam, croissant, etc., which have flowed from the production line, are put in a plastic case called Banjyu, and each block is placed in a block. After stacking about 20 steps and putting them on one stand in a state of being placed on a trolley, putting the same pools in a primary pool and putting them in a warehouse, look at the work slips and make a wide distribution space like a gymnasium every 2-3 stands. In addition to warehousing (allocating) to the sorting area, considering the order of loading and unloading with trucks, the weight is reloaded according to the number of bread orders at retail stores, and the sorting work of sorting is all done by human sea tactics. Was processing.

[0003]

In this case, the type and number of bread to be ordered are different every day at each retail store, and the holidays may be different depending on the store. Therefore, the order of delivery to each retail store is also different. Since it is necessary to perform sorting work while judging all of the slips, automation of this entire work is extremely difficult, and therefore the present invention provides a truck sorting device for sorting trucks for each product to predetermined places. This is to greatly reduce the number of personnel required for sorting work and to greatly improve the efficiency of sorting work itself.

[0004]

[Means for Solving the Problems] That is, according to the present invention, a carriage carried in at a carry-in position is conveyed to a carry-out position so that a preset arbitrary number of accumulators can be carried out, and a carriage stopped at the carry-out position. A storage conveyor that waits for a carry-out command to be carried out and a carriage from the storage conveyor are engaged with each other to convey the carriage along a preset track, so that the carriage is mounted so as to be circulatively driven along the track. A main conveyor on which a dog engaging with the truck is attached to the chain in correspondence with the conveyance pitch of the truck, and a plurality of sorting positions for the truck preset on the main conveyor are attached, Move the truck that has reached the sorting position to a position where the engagement between the truck and the dog is released and interference with other trucks that move with the main conveyor is avoided. A pusher device for moving, a truck sorting apparatus having a certain.

[0005]

When the trolley sorting apparatus of the present invention thus constructed is used in, for example, a bakery factory, various breads such as loaf of bread, bean jam, croissant, etc., which have flowed from the manufacturing line, can be used in several to several dozen pieces. After putting the stacking trolley placed on the trolley into the loading state, the worker looks at the slip and every 2-3 tiers. Then, the warehouse is unloaded at the sorting area, and the sorting position is designated and placed on a storage conveyor, for example, a belt conveyor-shaped storage conveyor having a transport surface formed on the same surface as the floor surface. Similarly, while the block stacking cart is unloaded, the sorting position is specified and placed on the storage conveyor, and the previously transported block stacking cart hits the stopper and stops.
When the carriage is ready to engage with the dog on the main conveyor, the carriage is unloaded onto the main conveyor and moves along the track of the main conveyor. During this movement, when the truck comes to the designated sorting position, the pusher device at this sorting position operates, and the truck is released from the engagement with the dog and moves together with the main conveyor in the state of being piled up in piles. Is moved to a position where it avoids interference with the trolley, and in the same way, each trolley in the subsequent stacking stack is sorted via the pusher device to the sorting position designated for each.

Next, the operation of this embodiment will be described with reference to the flow charts shown in FIGS. In the case of the truck sorting apparatus 1 configured in this way, the bread manufacturing line 2A to
Various breads such as bread, bean jam, croissant, etc. that came from 2D are put in the weight 3 by several to several tens, and one block is stacked in 20 steps to make one stand and placed on the trolley 4. After being put in the warehousing zone in a state where it is formed on the weight cart 5, the worker looks at the slip and unloads from the warehousing zone for sorting distribution every 2-3 stacks.
The weight cart 5 is placed on the table top chain 10 on the same surface as the floor surface 7 of the storage conveyor 6, and the sorting position of the weight cart 5 is set to 1ST on the main conveyor 22 using the data setting flowchart of FIG. ~ 7ST
Specify either.

That is, in step 101 of FIG. 17, the sorting distribution position is set to any of 1ST to 7ST, and it is determined in step 102 whether or not data is set.
In the data setting state, the data is displayed on a display (not shown) in step 103, and after it is determined in step 104 whether or not the data correction effective time has elapsed, the data is fixedly stored in step 105. In the same manner, the loading carts 5 are sequentially loaded and placed on the storage conveyor 6 by designating sorting positions, and the loading cart 5 previously conveyed hits the roller-shaped stopper 14 at the unloading end of the storage conveyor 6 and stops. 18 in the state
According to the flow chart shown in FIG. 4, when the heavy load cart 5 becomes engageable with the dog 21 on the main conveyor 22, the heavy load cart 5 is unloaded onto the main conveyor 22 and follows the track of the main conveyor 22. To move.

That is, in step 201 of FIG. 18, whether or not the weight cart 5 has reached the carry-out end position of the storage conveyor 6 is confirmed by a limit switch (not shown) at the position of the roller-shaped stopper 14, and then carried out in step 202. It is determined whether or not the data of the sorting distribution position is set in the weight cart 5 at the end position, and in the state where the data is present, it is determined in step 203 whether or not the carry-in to the main conveyor 22 is OK. In step 204, the air cylinder 17 of the pusher device 16 is moved forward to engage and adsorb the weight cart 5 with the dog 21 and the magnet chuck 34 at the carry-in end position of the main conveyor 22, and then in step 205, the main conveyor 22. Confirm that the heavy cart 5 has been carried in to the
In step 206, the sorting distribution position data of the heavy weight cart 5 loaded this time is transferred to the storage conveyor 6 of the electric control circuit.
When it is transferred from the control area to the control area of the main conveyor 22 and whether or not the activation of the main conveyor 22 is OK in step 207, the pusher device 16 of the storage conveyor 6 is restored in step 208, and the succeeding weight cart 5 Are sequentially fed, and the same operation as described above is performed. On the other hand, when it is determined in step 301 of the flowchart shown in FIG. 19 that the takt time of the main conveyor 22 is up in the state where the heavy load cart 5 is carried in to the main conveyor 22, step 30 is performed.
In step 2, it is determined whether or not the pusher device 35 at each station position 1ST to 7ST of sorting distribution is in a fixed position, and in step 303, it is determined whether or not the pusher device 16 is in a state in which the main conveyor 22 can operate. In the enabled state, the main conveyor 22 is activated in step 304, and it is determined in step 305 whether or not the main conveyor 22 has moved by one pitch. When the movement of one pitch is confirmed, the operation of the main conveyor 22 is performed in step 306. Is stopped, the sorting distribution position data of the heavy weight cart 5 is also shifted all at once.

That is, as for the sorting and distribution position data of the heavy weight cart 5 on the main conveyor 22, a data storage register is allocated to each station position 1ST to 7ST, and each station position 1ST to 7ST is allocated every time one pitch of the main conveyor 22 is completed. The data stored in the separate storage register is also collectively shifted so that the position of the weight cart 5 on the main conveyor 22 and its sorting distribution position data are always synchronized. Thus, when the weight cart 5 comes to the designated sorting position, the pusher device 35 at this sorting position is placed.
Is activated, the heavy weight cart 5 is disengaged from the dog 21 in the heavy weight stacked state and the main conveyor 22
The weight carts 5 are moved to a position that avoids interference with other weight carts 5 that move together, and in the same manner, each of the subsequent weight stacks 5 of the weight stack is passed through the pusher device 35 to the designated sorting position. Be sorted.

That is, when the weight cart 5 is carried out at a designated sorting position, for example, 3ST, it is determined at step 401 whether or not there is data at the immediately preceding position, as shown in the flowchart of FIG. If yes, step 40
In step 2, it is determined whether or not the data is for 3ST, and if it is for 3ST, the main conveyor 22 is activated in step 403, and in step 404, a warning indicating that there is unloading is output through the speakers installed in each station. At the same time, it is confirmed in step 405 that the main conveyor 22 has moved by one pitch, the main conveyor 22 is stopped, and in step 406, the pusher device 35 at the 3ST position is moved forward to move the weight cart 5 at the sorting position 3ST to the 3ST position. After carrying out at the position, after the time of the carry-out confirmation timer at Step 407 has expired, at Step 408, the sorting position data of the weighted cart 5 that has completed carrying out is cleared, and at Step 409, the pusher device 35 is returned and the return is confirmed. In this state, in step 410, the return operation of the pusher device 35 is stopped.

As described above, in the case of the trolley sorting apparatus of the present invention, the type and number of bread ordered at each retail store are different every day, and the holidays may be different depending on the store. Different from each other, all of them require sorting work while judging by looking at the slips, so it is extremely difficult to automate all of this work, but trolley sorting in the form of replacing the manual work carrying with a machine as it is. Since the device is used, the flow of work between the manual work and the automatic sorting work by the machine is made smooth, and the efficiency of the sorting work itself is greatly improved in a state where the number of workers is greatly reduced.
